Modeling Smoldering Fires using the Computer Model CONTAM

Abstract

The computer model CONTAM was used to simulate the spread of smoke in a house with a working furnace during smoldering fires. Three smoldering experiments from a study on detector sensitivity and siting requirements conducted in 1975 using a two story brick house with a basement were chosen to model. The choice was based on the experiments having similar smoldering sources and location, a furnace that was operated in two of the experiments, the reported doors to various rooms being open or closed and the outdoor weather having almost identical conditions. All of these experiments were allowed to smolder for a substantial length of time and did not transition to flaming. The results of the modeling are compared with the experiments. CONTAM was not designed to model fire but with some recommended additions could become very useful modeling smoke spread from smoldering fires.
